Module: spring-kafka

[murdos]

The current kafka module use kafka-clients dependency, rather that relying on spring-kafka integration.

Spring-Kafka brings some interesting features (configuration by properties, observability, high-level abstraction, ...) and is what is used in projects I've worked on.

I think we should either replace the implementation of the existing module, or add a second one that uses spring-kafka.

The first one was coded by @fdelbrayelle : it can stay like this, until it's totally unmaintained and broken. Then we'll remove it if it's the case

So I would suggest to add a second one here
